Primary Open-angle Glaucoma Clinical Trial
Official title:
Combined Phacoemulsification and Viscocanalostomy With Ologen Implant Versus Combined Phacoemulsification and Viscocanalostomy
This prospective, interventional, randomized clinical study was done at Alpha Vision Center,
Zagazig, Egypt. Patients with coexisting cataract and glaucoma were randomized to receive
either phaco-viscocanalostomy (Phacovisco group) or phaco-viscocanalostomy with Ologen®
implant (OloPhacovisco group) . Follow-up period was 2 years. Nd:YAG laser goniopuncture was
done in cases where the intraocular pressure (IOP) was elevated above 21 mmHg after
discontinuation of corticosteroid eye drops at any follow-up visit.
Our hypothesis is that using Ologen® implant as a spacer in the subscleral reservoir in
phaco-viscocanalostomy reduces fibrosis and increase the success rate of this operation
Background: To study the efficacy of the biodegradable collagen implant Ologen® as an
adjuvant in phaco-viscocanalostomy in patients with coexisting cataract and primary open
angle glaucoma.
